Why do people look for alternatives to SendGrid (now Twilio SendGrid) is a cloud-based email API for sending transactional and marketing emails. It processes billions of emails per month with delivery optimisation and analytics.?
SendGrid has struggled with declining deliverability, slow support and unpredictable price increases after the Twilio acquisition. The dashboard interface is dated and the developer experience lags behind more modern alternatives.
